ASA H. ALLISON, OF MILLVILLE, INDIANA.

IMPROVEMENT IN GATES.

Specication forming part of Letters Patent N 0. 219,194, dated September 2, 1879 application filed July 15, 1879.

To all whom it may concern:

Be it known that I, ASA H. ALLISON, of Millville, Henry county, State of Indiana, have invented a new and useful Improvement in Gates, of which the following'is the speciication.

rlhe object of my invention is a sliding gate, constructed as fully described hereinafter, so as to reduce friction and permit easy inanipu lation.

.In the drawings forming part of this 'specificatiou, Figure 1 is a perspective view of my improved gate, and Fig. 2 is a plan view.

A A' and B B' are parallel uprights, sup.

ported by cross-sills I I'. A` Between the uprights, and in slots in the sills I I', and iu a cross-bar, J, extends a metal rail, D, resting with its lower edge on the ground, highest between the uprights B B', where it has a notch, a., and projecting beyond the uprights A, as shown.

Ihe gate consists of standards C E G and cross-bars F, and rests upon a grooved wheel, b, running upon the rail D, and having its bearing upon a pin,'e, extending through the central standards, Gr.

A pin, t', extends through the standards C, near the lower end, and a guide, u, secured at the lower end of the standards E embraces the edge of the rail D.

The gate carries an adjustableweight, W, arranged above the central wheel, b, by means of which the gate may be balanced or tilted to either end, as described hereinafter, a pin, s, securing the weight after adjustment.

When the weight is centrally arranged, as shown in Fig. 1, the gate is evenly balanced, and its weight rests wholly upon the wheel b, so that the gate may be moved back and forth with but little friction, a cross-piece, d, connecting the uprights A A', having a notch to receiveA the upper rail, F, and thus guiding the gate.

When the gate is brought with its standards C between the uprights B-.B' the pini will strike the inclined edge of the rail D, and will slide upon the latter until it falls into the notch a, when the gate will be retained in its position.

In order to lock the gatemore securely, the' aid iu carrying the gate to the position shown' in Fig. l. l

The weight, when moved toward the standard E, causes the gate to press heavily with its ,guide n upon the rail D, creating such friction as will hold the gate in place.

To protect the rail D without interfering Y with the operations of the gate,inclined bridgeboards K K' are arranged with their inner edges adjacent to, but above, the edge of the blade, as shown. i

1 claim- 1.'The combination of the uprights A A' B B', rail D, elevated and notched at one end, and gate provided with a central grooved wheel resting upon the rail D, and with a guide, a, and pin t', as set forth.

2. The combination, with the gate, its central supporting-wheel, and notchedrail D, of the adjustable weight W, as specified.

3. The combination ofthe notched sills I I', crosspiece J, rail D, carried thereby, and sliding gate supported centrally on the roller b, substantially as set forth.

4. The combination of the sliding gate sup* ported by its central roller, b, of the uprights A A' and cross'piece d, having 'a notch to receive the upper rail of the gate, substantially as set forth.

5. The combination of the gate., its central wheel, b, pin fi, and the rail D, having a raised end and notch a, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
